But using that to reason about "wrongness" still seems backwards.

"This is bad in a way similar to how littering is bad, therefore it should be discouraged (and maybe banned) like littering is discouraged and banned." is a perfectly reasonable form of argument. "But it's not banned like littering is banned!" is not a good objection.

It is, of course, possible that it's not actually bad like littering is bad, or that other concerns genuinely override... but that doesn't make this particular objection appropriate.
